The Perfect Combination

Lightweight, compact and fuel efficient.

Enhanced Durability

A proven 498cc two-cylinder, SOHC design features a new cylinder block and head. The pistons, connecting rods, and valves are the same as used in its F60 big brother, for added strength, responsive power and excellent fuel efficiency in a compact package.

Greater Reliability

New electronics and a new micro-computer controlled ignition system mean dependable starting and consistent power, while an advanced air intake system drains away any water that enters the cowling during normal engine operation for long-term reliability.

Responsive and Fuel Efficient Power

A streamlined intake manifold uses long tracks and smoother airflow, for reliable and responsive power with outstanding fuel efficiency.

Smooth and Quiet

Engine exhaust is routed through a maze before exiting above the waterline through the idle exhaust relief outlet for unbelievably smooth and quiet operation.

Choice of Controls

Tiller handle models feature improvements in strength and operator comfort, with stronger components and improved grip. Our Multi-Function tiller is also available as an option on remote control model.

Waist Driveshaft

A specially-designed driveshaft that is narrow in the centre section and thicker on each end. This helps the driveshaft to temporarily flex when the propeller strikes a hard object reducing the risk of damage.

F9.9

Conquer Water

We took the popular F9.9 and completely redesigned it to offer even greater efficiency and enhanced features, all built into a smaller and lighter unit. In fact, the F9.9 is nearly identical to our previous 9.9 two-stroke in size. This helps makes it the ideal lightweight outboard companion, promising the legendary Yamaha reliability over a million boaters have come to depend upon.

Better Starting

The Perfect Combination

PAD & FOLD

An added resting pad means more storage options and improved storage stability, while the redesigned tiller handle allows the stored motor to take up less space.

WITH A TWIST

The driveshaft on the new F9.9F and T9.9G has a special centre section that is narrower than the ends. It is designed to temporarily "twist" should the prop coming into hard contact with an underwater object, protecting the powerhead, propshaft and other vital engine components.

CONTROL

The shortened tiller handle is now easier to use than ever before. Its new shift level shape provides better grip for precise shifting.

T9.9

Conquer Water

The T9.9 has been completely reworked and designed into the smallest four stroke in this class. It has all the features found in the F9.9 plus the additional benefits of Yamaha's exclusive high-thrust drive system, making the T9.9 the ideal choice for kicker, pontoon or any application where lightweight torque is required in both forward and reverse.

RESPONSIVE POWER

The overhead camshaft design efficiently exchanges intake and exhaust gases for responsive power and fuel efficiency.

PAD & FOLD

An added resting pad means more storage options and improved storage stability, while the redesigned tiller handle allows the stored motor to take up less space.

WITH A TWIST

The driveshaft on the new F9.9F and T9.9G has a special centre section that is narrower than the ends. It is designed to temporarily "twist" should the prop coming into hard contact with an underwater object, protecting the powerhead, propshaft and other vital engine components.

MORE REVERSE THRUST

Yamaha's unique dual-thrust propellers are designed to redirect the exhaust flow away, thereby reducing cavitation. This feature provides up to 60% more thrust in reverse.

SMOOTH & QUIET

The T9.9 is among the quietest engines in its class thanks in part to a single-latch sealed cowling, labyrinth exhaust and a water-sealed exhaust tube ? which provide excellent sound dampening. A long-span mounting system with large rubber engine mounts helps reduce vibration and noise.

F8

Conquer Water

The new twin-cylinder F8 still offers the benefits of fuel efficiency, quiet running and light weight, while getting a host of new ergonomic improvements and a new look. Best of all, displacement is now up 7.5 per cent for more torque and thrust.

LIGHTWEIGHT, PORTABLE POWER

Weighing in as light as 60 pounds, these 139cc OHV single-cylinder four-stroke powerhouses offer a CDI ignition system, optimally balanced crankshaft, long-span mounting system, labyrinth exhaust and a host of other features for smooth, quiet power. They even have built-in carrying handles for true portability and convenience.

MAXIMUM EFFICIENCY

The carburetor and its setting is factory-selected for maximum fuel efficiency, helping these outboards achieve a 3-star C.A.R.B. emissions rating. Additionally, automatic decompression, built-in auxiliary priming, and start-in-gear prevention help make for easy, safer starts.

CONVENIENT CONTROL

Control is key with a dynamically balanced and dampened large twist-grip throttle, 180-degree steering, and large F-N-R shift handle.

RELIABLE OPERATION

EASY STORAGE

This Yamaha exclusive feature provides peace of mind when storing or carrying the engine to and from the water. It allows the engine to be stored on either side or on the front grip without any fear of oil leakage, ensuring the engine is easy to start the first time out.

SMOOTH STARTS

A small auxiliary prime pump is fitted to the fuel pipe before the carburetor in the cowling. By ensuring the delivery of fuel to the carburetor, the engine can be started smoothly even after long-term storage.

MINIMIZING ENGINE WEAR

A pressurized oiling system minimizes engine wear for extra-long engine life.

VERSATILE PERFORMANCE

A 5-step trim adjustment couples with a 3-step Shallow Water Drive System to help make these outboards perform in various conditions. A splined propeller shaft and an expanded selection of available propeller sizes give you performance that's versatile and easy to handle and operate.
